In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the directionvof the little arrows at the ends of the section lines.

Referring t0 the drawing, the base or bed plate 1 is, in practice, mounted on a table or suitable support, not illustrated. 2 represents the crank of the power or drive shaft. The hopper 3is supported on brackets 4 so as to overhang parts of the mechanism. i

The cartons 5 illustrated are arranged in the hopper in the knockdown or fiat condition, the; cartons illustrated being such as are quite Vgenerally used for bottles and are scored so that they may be retained in set up forni by the .fiaps at one end. I have corresponding to `shown'the cartons mainly in conventional form and those illustrated are provided with opposed inner fiaps 6 and an outer flap 7 having a tongue 8 adapted to betucked into the carton at the edges of the inner flaps in the well-known manner, my machine being designed toset up 'and close one end Vof a carton ready to receiveV the bottle or package which it is to contain.

The cartons are discharged from the hopper `one by one into the setting up mechanism consisting of a fixed abutment '9 and the swinging angular set up member 10 which is pivoted on the base at 11. These members are disposed oppositely so that the Y cartons are discharged from the hopper with one longitudinal edge lying in the angle formed by the abutment member 9 and the base and the other upon the member 10 near the angle thereof,see Fig. III. When vthis member 10 is actuated it Vengages the edge of the collapsed cartonv and swings the same upwardly and presses inwardly thereon and, Owing to the cartons being previously scored along folded lines, it is expanded or set up as indicated by dotted lines in Fig. III.

p lThe set up member 10 is provided with an arm 12 projecting downwardly through a slot 13 in the base plate 1,*see Fig. XV.

' stroke.

This arm is connected by the link 14 to a lever l5 pivoted at 16 on the under side of the base plate. This lever is actuated by the cam 17 on theactuatingmember 28 which is reciprocatingly mounted on the under side of the bed plate. The lever 15 is provided with a roller 19 adapted to travel on this cam 17.

To provide a gradual closing movementV ,of the lever is substantially uniform. lVhen the roller passes over this bridge piece on the forward or work stroke the bridge piece, which is carried by the spring 22, swings down VSo that on its return the roller drops into the recess providing a quick return movement for the setting up member 10, the return being' eifected by the spring 23 connected t0 the base plate at 24 and to the lever in front of its `pivot 16,-see Fig. V.

On the under side of the bed 1 is a way comprising a pair of members 25 for the outer fiap folder slide or carriage 26. This carriage 26 carries a way 27 for the inner actuating slide or member 28. The operating pitman 29 is connected to this actuating' member 28 at 30. The actuating' member 23 has a lost motion connection to the flap folder carriage 26, the carriage 26 being provided with a pin 31 and the actuating member 28 with coacting stop or abutment members 32 and 33,-see Figs. XII and XIIA. i

The folder carriage 26 carries a bracket 34 in which the shank 35 of the outer fiap folder 36 is slidably mounted, the lbracket having a pair of upwardly projecting arms 37 and 38 with alined holes therein for the shank of vthe fol-der. The shank of the folder is provided with a stop 39 which engages the end 40 of the slot 41 when the folder 36 reaches the end of its forward The folder -36 is rearwardly curved so that itengages the end of the outer fiap and as the folder moves forwardswings it downwardly and turns its tongue inwardly, the folder ybeing provided with a tongue guide or tucker 42 which enters the carton guiding the tongue S into the carton between the edges of the inner flaps 6 and the adj acent wall of the boX.

To completely close the outer Hap I pivotally mountva Hap closer 43 on the folder 36 at 44 so that it may be swung down at each side of the folder, the flap closer. being' bifurcated as shown in Fig.` I. This flap closer 43 is actuated by the pushers 45 mounted on the sides lof the arms 37 and 38 of the folder Lenser Supportingbraket :.314 tongasejproietons 4:61 on theE ,flap` closer, L i, The iiap .folder- 36l being; slidably supported ,on its.l carriage .is stopped .when itsgstop 39.v engages the stopIlLO4 1 on .the vbed plate; so that, on;A the continued Whichlspringis -adjustedwbysthe nut. 48

V These are, in practice, spring members mounted. on, post s52. and 53,respectively, projecting.. through .slots 54 and ,55 in the base plate 1. Theseposts arecarried bylinks 56 andfengage `slots 58 and 5 9 in, the: bell crank leversv 60.,l and 61, respec,

tively. Y These levers. are pivoted `at 62 and 63, respectively@ to arms `64 and 65 onthe slides 66and 67. The links 56 and 57. have slots" 68 therein engaging` pins 69V oni the levers. so that when the slides,` are actuated thepost-s 52 and `53 aresyyung in their ,slots and give a limitedpivotal.movement the movement beingitimed so'that first j one of the inner flaps is foldedandthen the other.4

is.v folded thereon. The slides 66 andGT .are

disposed oppositely on opposite sidesof the actuating' member; 2S.

The slide is supported .bythebracket 70 at its rear sideandalso the slotted stop.

or dog lslidably supported inthe bracket 72 and urgedjyi'eldingly `inward. by vthe springv 73. This stop or dog` ,71 is adapted to coact uv'itghthe notch or.l keeper 74 on `the slide. VThe slide.66 is alSO supported on its inner edge' byfajbil o ck'7 O n theactuating member Q8 isA a `spring@ressed pawl A76 adapted te engagea Atooth 77 @n uit aide ce andcarry the `slide forward `until the pawl is released engaging with4 thetip 78 of the bracket 70;A which constitutes a trip.`

Prior toftheureleasing of the'pawl .76the catch .71, engagesjthe stop. 74:` retaining the sli de until lthe'dog 71, released. bythe kp'aivl Y 76 which constitutes a trip therefor. `Vihen released the slide' is quickly returned by means ofthe coiled spring 79.@onnected to the base 1 plate at SOQand" to the, arm 64 at S1.-l The slide 67, best shown inligsi and X, is similarly supported and actuated, the parts bein g of slightly j different proportions and somew'h atf differently, -positioned as the inner flap folders` are designed to `operate successively.

i The actuationofthesetting up `member lever.` and fthese .innen,flapi folders v and ,the outerV flap Vfolder is timed `so that the lsetting up member is actuated first. inner flap folders are then successively actuated and then, through the lost motion connection described, the outer flap folder and closer is actuated and returned during the forward stroke of the actuating member, While the setting up member and the ejecting means are actuated during the return strokeof the actuating member.-

`The ejecting member 82 is pivotally mounted at 83 on the slide or carriage Si mounted on the under side of the bed 1.

The springs 85 are secured at one end to' Fig. XIX.

The ejector is actuated and controlled by the extension bar 89 of the actuating memberQS, the forward end of the bar being supported by the bracket 90. This bracket carries 'the stop 91 with which the dog 92 on' the ejector slide engages when the ejector is fin its retracted position. This dog is released by the cam 93 on the bar 89. The dog 9Qfis spring-pressed as is also the paivl 94 adapted to engage notches 95 in the bar for returning the ejector, the operation being as follows:

The parts are 'normally in the position shown in Fig. XX, the actuating member then being in its fully retracted position and the ejector in its actuated position. On thev return movement of the actuating member the paWl 94 engages with the notches 95 oflthe bar 89 carrying the ejector to its'set positio1i,-see Fig. XIX. lThe paw] 91tis released from the notch 95 by its engagement With the stop 91. The dog or `catch 92. rides over this stop and engages on the rear ,side thereof, thus holding` theejector in its return position under tension of the With-a Cani'97 coacting With an arm` 98 of the rock shaft 99 mounted on the under side ofthe bed in bearings 100,-see Fig. V.

The rock shaft 99 has an arm 101 engaging'a slot 102 in the bell crank lever 103 pivoted on a suitable hanger at 104 With one arm projecting through a slot in the bed 1.

VThis arm is connected by a link 105 to a bar-1ike cam member 106 slidably mounted in a suitable way 106 at the rear side of the carton hopper. This hopper is adapted to support the cartons in the fiat condition stacked one upon the other as shown in Fig. III. The cartons are fed vor discharged from the hopper one by one, the discharge mechanism consisting of coacting levers 107 and 108 mounted in pairs on pivots 109 and provided with carton engaging fingers 110 and 111, respectively, there being four of these pairs of levers disposed oppositely. The outer ends of these levers project at the ends of the hopper and are connected for simultaneous actuation by the crossed links 112, preferably having springs 113 therein. IVith this connection the four levers 107 are simultaneously actuated to and from carton engaging position, while the four levers 108 are similarly actuated. To actuate the levers to carton engaging position the cam member 106 is provided with cams 114, while the levers 108 are provided with projections 115 coacting with these cams. The levers 107 have projections 1'16 coacting with cams 117 of the cam member 106. The cam member 106 is provided with an adjustable stop 118 limiting its return movement, it being returned by the spring 119 connected to the bell crank lever 103 and to a bracket 120 on the bed 1. The discharge linger levers are retracted by the coiled springs 121 connected to the hopper wall and to the rear finger levers.

In the initial position of the parts as shown in Figs. III andIV the fingers 110 support the stack of cartons. When the finger levers are actuated from this position these fingers 110 are retracted and the fingers 111 projected, the fingers 111 being pointed so that they pass above the bottom carton of the stack supporting the stack, the fingers 110 being then retracted to discharge the bottom carton on to the fixed supports 122 at the rear and the swinging support 123 at the front of the hopper. The support 123 extends below the plane of the support 112 so that when a carton is discharged therefrom its front edge drops behind the abutment 9 before its rear edge drops on to the setting up member 10, as shown in Fig. III.

The support 123 is pivoted at 1211 and held yieldingly in position by the coiled spring 125 around its pivot. The support 123 1s actuated to release the carton by the discharge levers 107 at the rear, the support having .arms 126 engaging beveled ends or cams 127 on the levers so that when the levers are actuated to their supporting position the support 123 is actuated to discharge,

the carton and when the levers are retracted to discharge the carton the support swings to its supporting position.

The cartons are guided by the fixed guid es 128 and 129. On the bed are fixed positioning guides 130, 131 and 132. To insure the release-of the cartons from the fingers 111 I provide clearing springs 133 secured tothe hopper at their upper ends to proj ect-downwardly in proximity to fthe ngers 111.V These springs have portions 13a which engage on thelevers at their ends 108 so that when the levers are actuated the springs are pressed against the Vlower cartons of the stack. When the levers are retracted the pressure is released allowing the carton to drop on to the fingers 110 and clearing the fingers 111. The upper end of the hopper is supported by the uprights 135 mounted on the base bar 136.

Tith `this arrangement of parts the cartons are automatically delivered, set up,

and closed at one end.

To relieve the parts from undue strain in the event of clogging `I form the pitman 29 of Vsections-138 and 139, the section 139 having a sleeve 140 thereon slotted atlll to engage pins 1112 cn-the section 138. A spring 143 is disposed between the sections and is of such tension as to normally operate them but yields in the eventk of any mechanism becoming clogged or wedged.

I have illustrate-d and described my improvements in the form in which I have embodied the same for the setting up of cartons of comparatively small size.

I have'not attempted to illustrate or describel the various modifications and adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adaptthe same as may be desired.

`Having `thus described my invention, what I claim as new and desire to secure by Letters Patent, is: Y
